I hope it fits YOUR sktpo prescribed in YOUR pattern!

NOTE: the SKTPO is a decrease of 1 stitch. Does this seem reasonable according to your specific pattern? Is the pattern calling for some kind of shaping? OR, is your pattern creating yarn over 'holes' or 'eyelets' and following the yarn over eyelet...which adds a stitch...the SKTPO is the decrease counterpart? Is your pattern 'lacey' in appearance?

Ah so it is knit 2 together. Most instructions for that would read sk2po where the k2 is understood to mean k2tog. And this decreases 2 sts no matter how you write it. Slip 1, k2tog, psso - you start with 3 and end with 1.

It is reasonable for the decrease. The SKTPO is done at the top of the hat simply to decrease the number of stitches and shape the top of the hat. The pattern is not lacy. After the rows with the SKTPO the next rows are just following the pattern and calling for stockinette stitches. There are no increases. Thank you for your help.
